The technical solution of the utility model is realized in the following way: it includes a motor, a rotating shaft, a gear box and a container, and its improvement is that: the gear box is provided with a driving gear and a driven gear, and the driving gear The rotating shaft is connected with the motor, and the driving gear meshes with the driven gear; there is a material inlet at one end of the storage box, and a material outlet at the other end of the storage box. The inside of the storage box is provided with a rotatable helical shaft and a helical belt, the helical shaft is parallel to the helical belt, the helical shaft is connected with the driving gear through the rotating shaft, and the helical A number of helical shaft blades are evenly fixed on the shaft, and the helical belt is connected with the driven gear through the rotating shaft. A number of helical belt blades are uniformly fixed on the above described helical belt. The pitches of the shafts are different, and the blades of the helical belt and the blades of the helical shaft do not intersect.

In the above structure, the motor is a geared motor.

In the above structure, the spiral shaft and the spiral belt are parallel to each other and are horizontally arranged in the container.

In the above structure, the size of the helical belt blade is larger than the size of the helical shaft blade.

In the above structure, the pitch of the helical belt is greater than the pitch of the helical axis.

The beneficial effect of the utility model is that: the blades of the screw shaft and the blades of the spiral belt are different in size and pitch, but they do not intersect, have different sizes and different rotating speeds, and the spiral belt runs along the front and rear surfaces of the blades of the screw shaft when rotating. Movement, without contact interference, reasonable structure; while the screw shaft rotates to convey materials, the spiral belt blades can scrape off the materials on the front and back sides of the screw shaft blades at a low speed, so that the materials attached to the screw shaft blades It cannot be thickened, so that the purpose of automatic cleaning of the material on the blade of the screw shaft without stopping the feeder is achieved, and the production efficiency is improved.

【Detailed ways】

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

With reference to shown in Figure 1, a kind of self-cleaning screw feeder disclosed by the utility model, it comprises reduction motor 1, rotating shaft 23, gear box 2 and feeder 3, and described gear box 2 li is provided with driving gear 21 And driven gear 22, described driving gear 21 is connected with described reduction motor 1 by rotating shaft 23, and described driving gear 21 is meshed 22 with described driven wheel; The material inlet 31, the other end of the material holding box 3 has a material outlet 36, the inside of the material holding box 3 is provided with a rotatable horizontally placed screw shaft 32 and a spiral belt 34, the screw shaft 32 Located above the spiral belt 34, the spiral shaft 32 and the spiral belt 34 are parallel to each other, the spiral shaft 32 is connected with the driving gear 22 through the rotating shaft 23, and the uniform surface of the spiral shaft 32 is A number of helical shaft blades 33 are fixed, and the helical belt 34 is connected with the driven gear 22 through the rotating shaft 23. A number of helical belt blades 35 are evenly fixed on the described helical belt 34, and the helical belt 34 The pitch is greater than the pitch of the helical shaft 32, the helical band blade 34 and the helical shaft blade 33 do not intersect, the size of the helical band blade 35 is greater than the size of the helical shaft blade 33, and the rotating speed of the helical band 34 is smaller than that of the helical band. The rotational speed of the shaft 32 and the direction of rotation of the spiral belt 34 are different from the direction of rotation of the screw shaft 32 .

The utility model works like this: as shown in Figure 1, a spiral belt 34 (pitch 120mm, right-handed) is arranged below the helical shaft 32 (pitch 48mm, right-handed), and the helical belt 34 and the helical shaft 32 Driven by the same geared motor 1, the driving gear 21 and the driven gear 22 of the gearbox 2 mesh (center distance 56mm). Screw shaft 32 is rotated clockwise, and spiral band 34 is counterclockwise rotation, and the spiral band blade 35 of spiral band 34 (diameter 92mm) stretches into the edge place of the screw shaft blade 33 of screw shaft 32 (outer diameter 52mm), when deceleration The motor 1 drives the gear box 2, and when the driving gear 21 in the box drives the driven gear 22 (the gear ratio is 1:2.5) to rotate, the screw shaft 32 and the ribbon shaft 34 rotate at the same time, and the screw blade 35 of the screw belt 34 will be in the The positions about 2 mm from the front and rear surfaces of the screw shaft blades 33 of the screw shaft 32 move in circles, thereby automatically cleaning the adhered materials on the screw shaft blades 33 .
